GPS NAVIGATION
Airways which are classified in the database as all altitude routes will be drawn as high altitude routes
whenever both route types are selected for display at the same time. Otherwise, these routes will be
drawn in the style (low or high) that has been selected for display. The line drawn for an airway leg
that terminates at a VOR ends where the line intersects with the VOR Compass Rose unless there is an
adjacent waypoint on the airway that is drawn inside the compass rose. Lines drawn for airway legs that
terminate at other symbol types (NDBs or Intersections) end at a point that leaves a small gap between
the line end point and the symbol.
Airway Waypoint Symbols
When airways are drawn on the map, the symbols needed to show the airway waypoints (VORs, NDBs
and Intersections) are also drawn regardless of the map setting that would otherwise control the drawing
of that symbol. Labels (Identifiers) for VORs, NDBs and Intersections used on airways will always be
drawn according to the map settings for those items. For example, if airways are enabled to be drawn at
the 200 nm range setting, Intersection symbols will be drawn as needed to depict the airway even though
Intersections are enabled for display only for range settings of 30 nm or less. The intersection identifiers
will be shown for range settings up to 30 nm. Only the intersection symbols will be shown for range
settings greater than 30 nm. When airways are drawn on the MAP, all airway "optional" waypoints are
drawn.
Airway Labels
Airway labels are light gray rectangles with black text (colors will be similar to that used for national
highway labels) and are centered on the airway line. When several airways follow a common waypoint
sequence, the common sequence has multiple labels placed as close together as practical with only the
label border overlapping. To reduce clutter, some airways may not be labled.
